N-Sea expands its survey capabilities to offer a fully mobilised Shallow Geotechnical vessel in collaboration with GeoForce Technical Services
We are pleased to announce that N-Sea Group have chosen GeoForce Technical Services, part of Oceanscan and the wider Venterra Group, to support our growth ambitions through offering a fully integrated shallow water geotechnical solution on a dedicated vessel as well as across the N-Sea vessel fleet.
Beginning in Q2 2026, N-Sea and GeoForce will deploy a bespoke geotechnical package permanently integrated onto a N-Sea vessel, targeting offshore energy and transmission projects. This collaboration will provide clients with a reliable, mobilised geotechnical platform and removing the uncertainty and delays often associated with vessel of opportunity approaches.
As part of the scope, GeoForce will deliver end to end support through specialist geotechnical acquisition and analysis, including seabed characterisation, sediment analysis, core penetration testing and fully integrated deliverables to support ground model development. These insights will directly support route optimisation and installation design, giving clients a clearer, high-resolution understanding of subsurface conditions and derisking critical engineering decisions ahead of infrastructure installation. The work is essential to ensuring subsea infrastructure can be routed and installed safely, efficiently and effectively across varying offshore environments.
Patrick Defilet, Survey Director of N-Sea, said:
“We are excited to bring this collaboration with GeoForce to the market as N‑Sea expands its offering to clients in both Renewables and Oil & Gas. While we have delivered shallow geotechnical services on a project‑specific basis, this partnership enables a major step forward. By adding a permanently mobilised geotechnical spread to our in‑house geophysical solutions, we can provide a faster, more efficient and fully integrated platform, supporting our ambition to grow and diversify across the offshore energy sector.”
James McDonald, Managing Director of GeoForce Technical Services, said:
“It’s a pleasure to be selected to work with a company as ambitious as N-Sea. GeoForce will continue to invest in the latest equipment and technology to ensure this collaboration delivers a technically compliant, safe and highly efficient geotechnical platform. By permanently mobilising the vessel with an integrated geotechnical spread, together we remove the uncertainty of vessel‑of‑opportunity methods and provide a proven, ready‑to‑deploy solution.”
